Re: hpv and oral sex
Yes, you can still have oral sex. The HPV virus is very easily passed on from the genital and anal regions, so if you have it, your husband is sure to have it too. While HPV can cause warts in the mouth, that is a rare occurence. Having HPV in the throat does increase your risk of throat cancer, but it's such a rare cancer to begin with that it's really not something to worry about.
Kissing and sharing drinks with your children is fine.
